Participants

Conditions

Temperature: 20 °C

Procedure

Tert-butyl 3-[(5-{[bis (3-methylbutyl)amino]carbonyl}-2-nitrophenyl)amino]propylcarbamate (1.65 g) in solution in a mixture of ethyl acetate/ethanol 2:1 (130 ml), and 10% palladium on carbon (165 mg) are introduced into an autoclave. After stirring for 3 hours under a hydrogen atmosphere (3 bar) at a temperature of approximately 20° C., the catalyst is eliminated by filtration on celite and the filtrate is concentrated under reduced pressure at 40° C. in order to produce the expected compound in the form of an oil (1.35 g; 89% yield).
